NAME
FUNCTION
15
15
FB_LDO
LDO Voltage Feedback Input. Connect FB_LDO to SGND to select the preset +5V
output voltage. Connect FB_LDO to an external resistive voltage-divider for adjustable
output operation. See the
Setting the Output Voltage
section.
16
16
EN_LDO
Active-High LDO Enable Input. Connect EN_LDO to IN or to a logic-high voltage to turn
on the regulator. To place the LDO in shutdown, pull EN_LDO low or leave unconnected
and leave
HOLD
unconnected. EN_LDO is internally pulled to SGND through a 1μA
current sink. See the
Control Logic
section.
17
17
EN_TRK
Active-High Tracker Enable Input. Connect EN_TRK to IN or to a logic-high voltage to
turn on the tracker. Pull EN_TRK low or leave unconnected to place tracker in
shutdown. EN_TRK is internally pulled to SGND through a 1μA current sink.
18
—
EN_PROT
Protector Enable Input. Drive EN_PROT low to force GATE low and turn off the external
n-channel MOSFET. EN_PROT is internally pulled to SGND by a 1μA sink. Connect
EN_PROT to IN for normal operation.
19, 20
19, 20
IN
Regulator Input. Bypass IN to SGND with a 10μF capacitor (ESR
≤
1.5
Ω
).
21, 22
21, 22
OUT_LDO
LDO Regulator Output. Bypass OUT_LDO to SGND with a low-ESR capacitor with a
minimum value of 22μF. Fixed +5V or adjustable output (+1.8V to +11V). See the
Setting the Output Voltage
section.
25
25
HOLD
Active-Low Hold Input. If EN_LDO is high when
HOLD
is forced low, the regulator
latches the state of the EN_LDO input and allows the regulator to remain turned on
when EN_LDO is subsequently pulled low. To shut down the regulator, release
HOLD
after EN_LDO is pulled low. If
HOLD
functionality is unused, connect
HOLD
to
OUT_LDO or leave unconnected.
HOLD
is internally pulled up to OUT_LDO through a
0.6μA current source. See the
Control Logic
section.

FB_TRK
Tracker Amplifier Feedback. Connect FB_TRK directly to OUT_TRK or through an
external resistive voltage-divider.
30
30
TRACK
Tracker Input. Bypass TRACK to the SGND with a 3.3μF ceramic capacitor.
EP
EP
EP
Exposed Pad. Connect EP to SGND plane. EP also functions as a heatsink to maximize
thermal dissipation. Do not use as the main ground connection.
